MACHiNE FOR PRINTING IN COLORS.

SPECIFICATION formingpart of Letters Patent No. 618,252, dated January24, 1899.

Application filed December '7, 1896. Serial No. 614,825. (No model.)

To all whom it may concern.-

Be it known that I, J ULES MEYRUEIS, a citizen of the French Republic,and a resident of Paris, France, have invented certain new and usefulImprovements in Color-Printing Machines, (for which I have obtained apatent in Great Britain, No. dated December 5, 1895,) of which thefollowing is a specification.

This invention relates t0 machinery for printing, which may be used forprinting in one or different colors on one orboth sides of the paperwhen a continuous roll of paper is used for the paper-feed and forcutting off or severing the printed sheets and stacking the said sheets.

The general object of this invention is to provide a machine in which avariety of printing may be effected and in which when printing in colorsis to be performed a true register of the different colors may beproduced without delay or difficulty and correctly retained throughoutthe process of printing. In order to obtain this result, the inventioncomprises means whereby all parts of the continuous roll of paper, whichI hereinafter term the web,

. remain constantly subject, so far as possible,

where the lengths, directions, and modes of pressure upon the paper varysubstantially in the course of travel of the web from oneprinting-cylinder to another; and the essential principle of thismachine consists in the obviation of the difficulties arising fromunequal and varying resistances and pressures by means of the similarityin the distances and relative positions of the similar parts of themachine which arises from the nature of this construction, ashereinafter more particularly described. As a consequence of the similardisposition of the parts of the machine the web of the paper also in itscourse of travel remains subject to constantly similar conditions bothas regards the various lengths of unsupported travel and as regards thedegrees of strain and pressure incident to the direction or manner inwhich the continuous web approaches or recedes from each separateprinting-cylinder until the printing on one side is completed, afterwhich the web is again subject to similar and equal tension during theprinting on the other side. A difficulty in continuing to retainacorrect register arises from the cumulative effect of irregularities inworking when the machine contains a diversity or a complication ofmechanical parts. By my present invention I have also reduced thenumber, the complication, and the diversity of the mechanical parts to aminimum, and I have thus, in addition to attaining the principal objectof a correct register, succeeded in devising a machine which can be.

constructed with great precision at a comparatively small cost and whichfor the same reason can be worked at much greater speed and with muchless expense in labor and material than is usual.

Partly in consequence of the similar disposition invented I am able toarrange the cylinders, the stretching-rollers, and other principaladjustable parts of the machine in such a manner that they are readilyaccessible and each of them easily adjusted even while the machine is inactual operation.

The accompanying drawings illustrate so far as will be necessary forthose having a knowledge of the art a machine constructed according tothis invention and having a capacity of five colors.

Figure 1 is a side elevation of the upper part of the whole machine.Fig. 2 is a similar elevation, on a larger scale, of one of the storiesof the machine. Fig. 2 is a plan view thereof on the same scale as Fig.2. Fig. 2 is a side elevation, also on a larger scale, of thedriving-gear at and below the lowest story of the machine. Fig. 2 is aplan view of this gear. Fig. 3 is a cross-section on line 3 3, Fig. 2.Fig. 4 is a cross-sectional view on line 4 a, Fig. 2. Fig. 5 is across-sectional view on line 55, Fig. 2, Figs. 3 to 5 being on a largerscale. Figs. 6, 7, 8, and 9 illustrate diagrammatically arrangements forvarying the travel of the web, hereinafter referred to. Fig. 10 is across-section on line 10 10 of Fig. 11; and Fig. 11 is a longitudinalsection on line 11 11 of Fig. 10, showing the construction of theprinting-cylinder. Fig. 12 is a side elevation of the ductor-roller andadjacent parts. Fig. 13 is a plan of the cutting-knives. Fig. 14 is anend elevation on the side of the machine opposite to that shown in Fig.1.

Fig. 15 shows the fly-operating mechanism in side elevation. Fig. 16shows part of the fly and adjacent parts in front elevation.

The machine shown in the drawings comprises a base-plate continuedupward on each side in the form of columns P, which carry thecross-frames of the stories, (marked I II III IV V.) Each frameessentially comprises two rabbeted beams T, on which slide the supportsS S S of the printing-cylinders B, of the impression-cylinders A, and ofthe inking-train, respectively. Each of these superposed frames, withthe gear upon it, furnishes the impression of one color, the number ofsuperposed frames being equal to that of the colors to be printed.

Between the stories are guides carrying the stretching-rollers, of whichthere are usually two for each storynamely, G and H. Each story issimilar to the next, and consequently all the printing-cylinders are inone plane, all the impression-cylinders in another plane, and thecorresponding stretching-rollers are in another plane or planesthat isto say, approximately in such planes allowing for adj ustmentthe planesbeing parallel to one another and vertical in the machine illustrated.

As an example showing the comparatively small size of the machine itwill be seen that in a machine having printing-cylinders of two feet incircumference capable of being replaced by cylinders with acircumference of three feet the dimensions of the printingmachine(excluding the cutter and fly) would scarcely exceed six feet in heightby five feet in width, with a depth of about three feet. The greateststretch of unsupported web in its travel from one cylinder to anotherwhile being printed on one side scarcely amounts to half a foot, and theapproach of the web to the impression-cylinder and its recessiontherefrom are in such a direction that the impression-cylinder exerts aspeed-regulating pressure upon it over two-thirds or thereabout of itscircumference. Each printingcylinder B is secured on its axle b by meansof screw-nuts b, engaging screw-threads on the axle b, to permit ofdisplacement of the cylinder along its axle, as shown more particularlyin Fig. 3.

For the printing of several colors each by a difierent story of themachine the lateral register is regulated by displacing theprintingcylinder B longitudinally upon its axle; but if upon thiscylinder there are seve ral-different stereotypes each requiring for itsadjustment an amount of longitudinal displacement different from theother formerly one had to remove and refix each stereotype separately inorder to give a true register to each of them, which is a delicateoperation and requires time. I remedy this inconvenience by composing myprinting-cylinder of four sectors A A A A movable on a core A, throughwhich passes the drivingaxle I). These sectors are each adjustableparallel to the axle by means of the regulating-screws A which allow ofchanging the position of any of the sectors without touching the others.These sectors are also adjustably secured, so that they may be displacedin direction of the circumference. This is permitted without hindrancefrom the screws A since the latter pass through elongated slots in theend flanges of the core A and so are enabled to move circumferentially.Screws A A", passing through slots in the said flanges and engaging withthe sectors A A A A respectively, also participate in thecircumferential movement and after adj ustment of the sectors arescrewed tight to hold the sectors in the position previously given tothem. One can thus regulate any of the stereotypes in the two directionswithout losing time and without touching anything else in the machine.

The impression-cylinder A, which carries the paper and brings it incontact with the printing-cylinder B, is also mounted on ascrew-threaded axle a and secured by means of screw-nuts in order thatit may also be adjusted in like manner to the printingcylinder B, sothat the contact of the same points of the circumference of cylinders Aand B may be assured.

The base of each support S overlaps the edge of the beam T, beinginclined inward thereunder 011 one side to engage under the dovetailedtop of the beam and spaced at the other side to receive between it andthe side of the beam a key W. A similar construction provides for theguiding of the supports S and S on the beam, and set-screws WV areprovided, the ends of which bear against the side faces of these keys TVfor holding the supports securely and firmly when they have beenadjusted to the positions desired. The supports S and S are adjusted bymeans of screws u c, by means of which they may be respectively causedto approach or recede from the supports S, so as to cause the requisitepressure between the impression-cylinder and the printing-cylinder, onthe one hand, and between the inking-train and the printing-cylinder onthe other hand. These screws '17 Q2, respectively, are journaled inopposite ends of the beams T, which are hollow and have at suitableplaces slots cut in their upper faces through which project lugs s onthe under sides of the supports S S having screw-threaded holes forpassage and engagement of the screws 1; v. The exterior ends of thescrews t' n have square heads, on which cranks 0r hand-wheels may befitted.

It will be seen that in the case of a slight defect occurring in theregistering of any cylinder a correction mayimmediately be made withoutstopping the machine by the adj ustment either of theimpression-cylinder or of one or both of the stretching-rollers.

The course of travel of the web is also capable of modification by theomission of the use of the lower set of stretching-rollers in cases whenowing to the fineness of the paper it may be desirable to reduce itsmanipulations to a minimum.

I may use any convenient inking-train. That illustrated in the drawingscomprises an ink-trough m, feeding, by means of the roller 1, theductor-roller E, which transfers the ink to the roller E whence itpasses consecutively to E to E and to the cylindrical table 0. The shafta of the table 0, which is journaled in the pillow-bearings S Fig. 5, onthe support S carries a drunken disk a which engages with the flangedsleeves a c on the shafts a a respectively, of the inkspreading rollersE E". The shafts o a have rotary bearing and also endwise movement inblocks a a, adjustable by screws a in guides in the plate a carried bythe standard a on the support S The ink is transferred from the table Cto rollers E E rollers E' E and from there to the rollers D D D whichhave contact with the cylinder 13.

The followingis the gear by which the printingcylinders and adjacentparts are connected. The axle b of the cylinder B carries gear-wheels 1Py, of which wheel 3 meshes with a gear-wheel 3 on the shaft of cylinderA. This pair of gear-wheels is replacable by a pair of wheels of othersize corresponding to the cylinders when the latter are changed. Thegear-wheel y is driven by power, as hereinafter described. On shaft b isalso a wheel 1 geared by chain 3 with a wheel 3 on the axle of of thetable C, and on the said axle is also a wheel y, geared by chain y towheel if on the stub-shaft t the wheel 3 carrying also a spur-wheel 2'gearing with a spur-wheel on the shaft of roller 1. When theprinting-cylinder B is driven in the reverse direction for the purposehereinafter described, it is necessary that the roller 1 should not bereversed. On the shaft (t of the table O is placed another wheel if,which may be geared by chain 1 direct to another wheel y" on the shaft2' of roller I,this chain being brought into operation while the chain 1is taken olf or put out of operation in order that means may be affordedfor revolving the roller 1' in the same direction, whichever be thedirection of rotation of the cylinder 13. The bearings or trunnions ofrollers D D are mounted in arms (1 d pivoted at e to the frame S andhaving curved slots d through which pass screw-bolts (Z on which nutsmay be screwed. The trunnions of roller D are mounted in sliding bars (1having each a slot (ZQtraversed by a screw-bolt (1 By this constructionthe rollers D D D may be adapted to cylinders B of different diameters.The ductor-roller E is carried by arms 6 against which press'springs etending to press the roller E against the roller 1. On the shaft of theroller 1 is a cam formed of two leaves i 2' of similar radius andadapted to be adjusted to more or less cover one another, so as to form,in effect, a single cam adjustable in the length of the arc of itsgreatest radius.

e is a slot in leaf "N, and e is a bolt traversing said slot and passingthrough a hole in leaf 1 e is a nut for tightening the bolt e, and thussecuring the two leaves of the cam against relative movement. (See Fig.14.) The cam meets roller e on the stud e on the arm 6 and presses theroller E into contact with the roller E for a period corresponding tothe length ofthe aforesaid arc. Such are the details as applicable tothe inking mechanism shown in the drawings; but if other inkingmechanism is used the gear will be correspondingly altered.

To gear each tier with that above, so that the direction of movement maybe similar or reversed, there is provided on the side of the beam T abar F adapted to slide with the axis of its length midway between theaxes of the cylinders B B of the two tiers and be secured by set screwsor bolts f f in slots f. This sliding bar F carries gudgeons f f f, onwhich revolve wheels f f f, the wheels f and f meshing with each. other.The wheel f and the pair of wheels f f are so proportioned to thespacebetween wheels y y of two adjacent stories and they are so spaced fromeach other and arranged to the one and other side, respectively, of theplane containing the axes of wheels y y that by a movement of the bar Fin the one or other direction the wheel f engages with the two wheels yy, or the wheels f f engage, respectively, with the two wheels yy. Inthe former case the wheels y y will rotate in similar direction. In thelatter case they will rotate in contrary directions, the surfacevelocity being equal so long as wheels y 3 are equal and wheel f equalto wheel f To provide for accurate adjustment of this gearing when thewheel axes Z) I) are not in the same vertical plane, the set-bolts ffmay pass also through vertical slots in the beams T or in adjunctsthereof, which, in addition to the horizontal slots f in the bar F willprovide for limited adjustment horizontally and vertically in thevertical plane of the bar F The lowermost printing-cylinder B is drivenfrom the main shaft J through spur-wheels y .2 and spur-wheel .2 on theshaft J. The shaft J also carries a spur-wheel J gearing with the wheelJ journaled in a movable arm J pivoted at J to the beam T and adapted tobe fixed in either of two positions, in each of which it engages withthe spurwheel 5 but in one of which the wheel J engages with a smallerspur-wheel J on the shaft J and in the other position the wheel Jengages with wheel J 9 of twice the diameter of wheel J To enable thisto be done, the width of wheel J is equal to the combined widths ofwheels J J, and the wheel J may be moved longitudinally on its shaft toengage either wheel J or J while still remaining in gear with wheel JThe shaft J 8 carries a helical knife K, and the proportion of theabove-mentioned gearing is such that when the wheels J and J 9 are inengagement the ICC knife-shaft J makes one revolution for eachrevolution of the printing-cylinders but when the wheels J 4 J 7 are inengagement the knifeshaft J 8 makes two revolutions for each revolutionof the printing-cylinder. On the support S is mounted an adjustablestationary knife L, forming, with the knife K, shears by which theprinted paper passing between the knives will be cut into separatesheets.

To permit of the adjustment of the knife L, it is fastened upon acarrying-plate L, the ends of which are provided with lugs L throughwhich the shaft L passes, mounted in the framework. In the block L abovethe shaft L which block is part of or fixed on the framework, arescrew-threaded holes for two set-screws L L the ends of which bear onthe plate L, the one near the cutting edge of the knife L, the othernear the rear edge of the plate. By adjustment of these set-screws theplate L may be rocked upon the shaft L and the edge of knife L may thusbe brought nearer to or farther from the axis of the rotary knife K.

In order to cut the paper without stopping it during the time of cuttingand in order to obtain a good square cut, it is indispensable that theline of contact of the two cuttingblades be inclined with regard to thepaper sheet and that this inclination be propor tional, first, to thelinear velocity of the paper in the machine, and, second, to the linearvelocity of the movable knife in the circumference which it describes.In this machine shown, the movable knife K being fixed in helical lineupon its axle J each of its points comes successively in contact withthe fixed blade L. If 0 0 represent the two extreme points of thehelical knife K, the plane containin g the axis of shaft J S and thepoint 0 will bear a certain angular relation to the plane containing theaxis of said shaft J 8 and the point c that is to say, the point 0 isdisplaced behind the point 0 by a circumferential distance the magnitudeof which may be expressed as a ratio to the whole circumference and maybe conveniently referred to as a circumferential displacement of thismagnitude. This circumferential displacement must be compensated for byan equivalent inclination of the axis of the rotary knife and with itthe axis-of the fixed knife, and this inclination must vary, first, withthe linear velocity of the paper, which velocity depends on thecircumference of the printing-cylinders, and, second, with the velocityof the knife, which may be geared to revolve once or twice for eachrevolution of the printing-cylinders and so out once or twice for eachrevolution of the said cylinders. If the circumferential velocity of theknife equals the linear velocity of the paper, the elevation of one endof the knife above the other end equals the circumferential displacementbetween its two ends. Therefore if for cutting twice for each revolutionof the printing-cylinder the velocity of the knife is doubled, the

velocity of the paper remaining the same, the elevation of one end abovethe other is half of that required for one cut only. It is in effectonly necessary to lift or lower one end of each knife, preferably thatend remote from the gearing which drives the knife-shaft J3. The slightmovement of the gear-wheels J J due to the tilting of the shaft J is ofno consequence. The support K, Figs. 13 and 14, at that side of themachine remote from the gear-wheels J 7 J 9 is adapted to slidevertically and isprovided with a screw-threaded rod K allowing ofraising or lowering it at pleasure for regulating the inclination. The

form of these supports can vary; but what is important is the variationof the cutting-line,

as hereinbefore described, for rotary printing-machines and allowing afree cut with out indents and of square form obtained upon theprinting-machine without stopping the paper during the cutting, whichsimplifies the organs necessary for the cutting.

In the vertical plane above the shearingline meet two feed-rollers J Jbetween which the paperpasses, and above oneof these rollers is a thirdroller J around which the web passes from beneath the stretching-rollerG. The feed-rollers J J are driven one by means of a pulley J and a beltJ from a pulley J on the main shaft J, the other by friction from theformer. In the vertical plane close under the shearing-line meet thenarrow rollers m m and below, near the shaft of the fly, meet two otherrollers m m The rollers m of those two pairs of rollers m m which are atthe upper ends of the frames m are separately driven as follows: Theshafts J J of these rollers m m, passing through the frames m m, areprolonged also to pass through and project beyond the fixed side framesof the printing-machine. On the parts of the shafts J J thus projectingoutwardly beyond the side frames are pulleys J J", respectively, (seeFigs. 2 15, and 16,) driven by crossed belts J J from pulleys J Jrespectively, on the shaft of one of the rollers J. The pulleys J arekeyed on the shafts J so as to be capable of sliding endwise thereon,or, more strictly speaking, of remaining stationary, while the shafts Jare slid endwise when the frames m are moved to or from one another toaccommodate different widths of paper. Around these rollers m m passesan endless ribbon m and a similar ribbon m passes around the rollers m mThese two endless ribbons are stretched by rollers m m A similar set ofrollers is arranged on each side of the machine, each set being carriedby a plate m mounted in a sliding bar or bars m to permit of adjustingthe two sets of rollers nearer to or farther from each other, accordingto the width of the paper, the edges of which are held and drawndownward between said ribbons.

In the frame of the machine is the shaft 1' of the fiy B. This shaft isscrew-threaded, and on it are run the nuts 0*, which hold pressedbetween them the bosses r of the bars r. These bars extend radiallyfromthe shaft '1', and to the latter is given a rocking movement through onehundred and eighty degrees, or thereabout, by which the bars 7- arecaused to take the sheets of paper out off by the knives alternatelyfrom the one side and the other and deposit them alternately to theright and left. By thus placing the fly immediately below the knives thepaper passes directly to the fly and no intervening carrying mechanismis required, thus reducing expense. By depositing the sheets in twoheaps the fly has ample time to return from its lower position on eitherside while the next following sheet is descending, so that rapid andjerky move-' m ent of this part of the mechanism is avoided, enablingthe machine to be run at a quicker rate and with greater steadiness thanwould be the case if the fly-arms had to make a quick return movement topass to the farther side of the next sheet of paper before it descends.An adjustable ledge Z permits of the fly receiving sheets shorter thanits full length.

On the end of the shaft r is a gear-wheel or sector It, with whichmeshes a larger wheel or sector R having on it an eccentricallyplacedwrist-pin r, embraced by the end of the connectingrod 7, by whichoscillating movement is given to the sector R The rod 4' is driven by aneccentric r on the shaft 0". The shaft 7* is driven from the main shaftJ by gear-wheels The position of the bearings of the register-rollers isadjustable in such a manner that the distance traversed by the web inpassing about any one of them may be lengthened or shortened. This maybe done in various ways; but it is preferable that similar means shouldbe used for adjusting all the rollers D and similar means also used foradjusting all the rollers H, although the one means may be differentfrom the other. Thus the bearing 9 of the roller G may be adjustablehorizontally in the plate 77. of bracket h by means of screw it andhand-wheel 72. The bearing g of roller H may be adjusted vertically inthe guide 7L20 by means of the screw 7L and hand-wheel 7LT. At suitableplaces on the framework are bearings for the trunnions of the paper-rollor of the set-off roll or rolls. These bearings are indicated by M M MDP M ill. At the upper ends of the columns P and P are rollers 00 m :000 At each end of each story are also bearings (not shown) for thereception of the trunnions of rollers hereinafter referred to, such as SS, which may be shifted to different stories of the machine, asrequired.

I will now describe, with the assistance of Fig. 1 and of thediagrammatic views shown in Figs. 6 to 9, how the web may be printed onone or both sides. As an example, a fivecolored machine is shown, andFig. l illustrates the method of printing all five colors on one and thesame side of the web. Fig. 6

shows the method of printing four colors on the one side and one on theother. Fig. 7 shows the arrangement for three colors on the one side andtwo on the other. Fig. 8 shows a method of printing and rewindin g twoseparate webs, one in three colors and the other in two colors, whereinset-off rolls are used. Fig. 9 shows the perfecting of one web and theprinting of another web in one color on one side and in two colors onthe other side, set-off rolls being also used.

In the first example, Fig. 1, the roll is at M and the web passes overrollers 00 00 and thence downward between the printing and impressionrollers and around the registerrollers, commencing with the uppermosttier, as shown in dotted line in Fig. 1.

In the second example, Fig. 6, the web-roll is placed at M and the webafter passing the rollers 00 x m s and the register-roller G passesupward between the cylinders A B of the uppermost tier, thence over aroller at 8 back under the roller H, over the impression-cylinder of thesecond tier, thence over roller G of that tier, and so forth downward tobe out OK or to be rolled up at M, together with a set-oh web from aroll at M The rotation of the cylinders A B of the upper tier isreversed.

In the third example the web-roll is placed at M and the web passesaround rollers s G, upward between the cylinders A B,and around theregister-rollers of the two upper tiers, thence over rollers x 8 andback under the roller H, over the impression-cylinder of the third tier,thence around the register-rollers and impression-rollers downward.

\Vhere it is desirable to prevent soiling the impression-cylinders bythe contact with them of a web already printed on that side, a roll ofguard-paper called a set-off web is placed in the appropriate bearingand is led over the pressure-cylinder, being either again wound or cutoff with the web.

In the fourth example (shown in Fig. 8) the upper three stories are usedto print in three colors on one web drawn from roll at M and rewound atM,while the other two stories are used for printing in two colors onanother web drawn from roll at M and rewound at M At M and M are rollsof set-01f paper, which are wound up with the printed web at M and M,respectively.

In the fifth example(shown in Fig. 9)the upper two stories are used toprint on both sides of the web drawn from M and rewound at M, togetherwith the set-off web from M while the three lower stories are used toprint once on one side of another web and twice on the other side, thisweb coming from a roll at M and either cut off or rewound at M, togetherwith a set-off web from M The course of the web in these examples willbe obvious from the drawings.

In all the above, given as examples only, it will be noticed that solong as successive printings are being performed on one side of IIO theweb the angles or curves through which the web is turned and thedistances from one to another of the rollers carrying it are the samebetween the different stories and that when the other side is to receivesuccessive printings the said angles, curves, and distances are againthe same. It will further be noticed that by the use of theregisterrollers G H for each story, placed in a plane parallel to butspaced laterally from the plane of the axes of the impression-cylinders,the web when in contact with the impression-cylinder has contacttherewith for about twothirds of its circumference and that even whenone register-roller only is used the lateral displacement thereof fromthe plane between one printing-couple and the next is such that the webhas contact with the impression-cylinder over nearly half thecircumference of the latter. By this means the slipping of the web onthe impression-cylinders is avoided, and since the strains on the paperare the same between each printing and the next on the same face of theweb the tendency to slip is also avoided,while the register-rollers arelocated in a most favorable position for adjustment to secure accurateregister of impressions and can be so adjusted while the machine isrunning. The movability of each bearing S S S along its supporting-framenot only admits of relative adjustment of the bearings to one another,but enables the whole set to be moved toward the one or other end of theframe, as may be required to give the maximum orminimu m stretch of webbetween each impression.

Having now described this invention, I claim in machinery for printingby successive impressions in one or more colors on one or both sides ofa continuous web 1. The combination of a series of printingcylindershaving their axes equally spaced from one another in one plane, a seriesof impression-rollers having their axes equally spaced from one anotherin a parallel plane, the surfaces of contact between said printing andimpression rollers being equidistant from one another and in a planetangent to the se ries of printing-rollers, a series of registerrollershaving their axes in a plane parallel to the aforesaid planes andsimilarly placed with regard to the axes of the respectiveimpression-rollers and at such distance therefrom on the side remotefrom the printing-cylinders that the web passing alternately around theimpression-rollers and the register-rollers has prolonged contact withthe former, bearings for said printing, impression, and register rollersrespectively and a series of juxtaposed parallel detachable frames suchas I, II, III, IV, V carrying respectively the bearings for each set ofprinting impression and register rollers.

2. The combination of a series of juxtaposed parallel and equidistantframes each constituting a slide-bed, a series of printingcylinders,bearings therefor adjustable longitudinally on said slide-beds, a seriesof impression-cylinders, bearings therefor adjustable longitudinally insaid slide-beds, to or from said printing-cylinders on one side thereof, a series of inking-trains adjustable longitudinally on saidslide-beds to or from said printing-cylinders on the other side thereof,a series of register-rollers G H and bearings therefor, the axes of theprinting-cylinders of the impression-cylinders and of theregister-rollers being respectively in three parallel planes, and theaxes of the printing-cylinder, impression-cylinder and register-rollersof each single set having relative positions similar to those of eachother set for the purpose set forth.

3. The combination with a base, a fly and cutter mechanism, of pillarsupon said base, and a plurality of horizontal superposed frames carriedby said pillars, printing-cylinders B bearings S therefor adjustablealong said frames, impression-cylinders A, bearings S therefor adaptedto slide on said frames, inking-trains and bearings S therefor adaptedto slide on said frames, screws 1; v for adjustment of bearings S and Srespectively, register-rollers G H, means for guiding a continuous webto the uppermost frame, and means for guiding the same from thelowermost frame to the cutter mechanism and fly, the said parts being soplaced that lengths of web between each printing-couple are equal anddeflected symmetrically through equal angles and so that the web hascontact with each impression-cylinder over a distance greater than halfthe circumference of the latter.

In witness whereof I have signed this specification in presence of twowitnesses.
